An unknown person or persons who sneak into frame and pose in the background of your photos. Often times the creeper makes faces or hand signals. Someone who tries to immortalize themselves in your photo album.
I thought I had this awesome picture of my girlfriend and Me at the "Rally to Restore Sanity" and when I got home and looked at it on the computer, some creeper was staring over my shoulder.
